I'm quite amazed at how active a crayfish is. I guess I was warped by all the lobsters I see in tanks up here into thinking they were slow and didn't move much. Never occurred to me that she (I think it's a she) would start climbing the fake plants. 
Also strange to see little crayfish footprints. All the pics I've seen were gravel, and I' have sand in the tank.
